I've been keeping an eye on Samson for a while now and whilst we still wait for the version 1 release the current version sports some interesting developments.
SAMSON is the quickly growing platform for molecular modeling. SAMSON's goal is to make it faster for everyone to design drugs, materials and nanosystems.
There are an increasing number of Elements
SAMSON Elements are modules for SAMSON that you add from SAMSON Connect. The first time you start SAMSON, some default SAMSON Elements are automatically installed
And the documentation now includes some tutorials, the GROMACS Wizard Light help you to easily run GROMACS simulations and get results as plots and simulation trajectories.
As I've mentioned before the Samson scripting API allows you to control Samson using Python.
